IPC: C09K3/22
Filed: 1983-01-13
Granted: 1984-05-24
Abstract: A process for producing pasty agents for binding dust in coal mining is described, which agents are obtained by stirring a mixture of aqueous magnesium chloride solution with calcium hydroxide to give a gel-like carrier material, into which the aqueous solution of hygroscopic salts and wetting agents is then stirred in, whereupon small quantities of liquid, acid sodium salts of polybasic phosphonocarboxylic acids are stirred into the pasty agent.

Title: Monitoring military exercises carried out by units - using clock-controlled radio recognition appts. with interrogating and answering units
Inventor: GRAMMUELLER HARALD DIPL-ING
IPC: F41G3/26
Filed: 1984-11-30
Granted: 1991-05-02
Abstract: Signal transmitting units are assigned to the weapon systems managed by those taking part in the exercise, appropriate to the scatter region, for the purpose of the angular definition of signals and to such signals the meaning of a 'shot' is given.  When a signal receiving unit assigned to a weapon system receives a shot signal, the event is recorded as a hit according to the radio data transmitted in temporal order. Clock-controlled radio recognition equipment with call and answer units is used for transmitting and receiving signals and for radio data transmission. A call signal with compatible coding is given the meaning of a 'shot' and another call signal also provided with compatible coding the meaning of a practice call for identifying an unknown target. The event and the meaning of the call signals are recorded with the exact time in a memory and, when an answer unit receives a shot signal or a practice call signal, the event is recorded in a similar memory at the exact time so that, by recording these times, the transmitting call unit can be tied to the receiving answer unit. ADVANTAGE - Performance of all participants can be assessed without error.

Title: Air bubble bath with admixture of additives to the bubbling air
IPC: A61H33/04
Filed: 1988-12-05
Granted: 1990-03-29
Abstract: In order effectively to be able to carry out, for example, an aromatherapy, which is effective in many vegetative syndromes, in an air bubble bath, a device (1) with housing (1a) and exchangeable cartridges (1b) is preferably inserted in the hose (3) between blower (2) and bubble mat (4). The cartridge (1b) releases, for example, bound gases which are admixed with the air stream to the bubble mat (4) by the Venturi principle. In the mat, they are released into the bath water and, on the one hand, they are dissolved and taken up by the skin of the bather and, on the other hand, they are enriched in the air over the water level and inhaled. Release and admixture of the gas/aerosol/steam/smoke or dust can be accurately controlled - where appropriate via remote control - by heating the cartridge (1b) and/or by a valve at the opening (1c). <IMAGE>

Title: Scanning ophthalmoscopy for obtaining retina images, by scanning lines of light on retina using linear sensor
Inventor: MENSINK MICHIEL HERMAN
IPC: A61B3/12
Filed: 2003-08-11
Granted: 2005-02-14
Abstract: Light source (20), sensor, gaps and imaging components are designed to produce confocal image. Light source is long light filament, elongated LED or elongated gas discharge lamp, or small point-shaped light source with high illumination, e.g. LED, superluminescent diode or laser diode, combined with optical components such as Powell lenses or cylinder lenses to create a thin beam. Gaps comprise transparent liquid crystal display (LCD) containing components electronically regulated to make them more transparent or darker. Sensor is area sensor of M * N CCD or CMOS elements, with area of interest J * K, whereby J is less than or equal to M and K is less than or equal to N. The retina image is obtained by a method comprising the following steps: (a) shining a beam of light through an adjustable gap; (b) directing the gap image onto the retina and reflecting the light using a scanner (movable mirror); (c) moving the scanner backwards and forwards across the retina; (d) capturing the reflected light and using the same scanner to descan the light in order to form a stationary beam; (e) optically focusing the reflected descanned light and partly reflecting the light towards a second gap using a partial mirror; (f) using the second gap to direct an image with a large number of pixels in the length direction and a small number of pixels in the width direction onto a linear sensor (60); and (g) converting the electrical signal from the sensor into an on-screen image. Independent claims are also included for the following: (1) Method for generating a high or low intensity image or light pattern on the retina; and (2) Method for detecting eye movement by comparing a retina image with a standard retina image. The method for generating the image on a retina comprises dividing the image into lines, using the lines to control a transmissive LCD screen from top to bottom, illuminating the lines, directing the lines onto the retina and reflecting the light using a scanner and moving the scanner backwards and forwards across the retina in order to recreate the image. The eye movement detection method involves compiling a standard retina image by analyzing a number of retina images in order to obtain two identical images which correspond to the eye being still and represent a standard image, compiling a retina image line by line, comparing the line in the image with several lines before and after it in the standard image and comparing the pixels with several above and below it in the standard image and using the line with highest degree of correlation to determine the direction and degree of eye movement.
